Luxembourg, January 31, 2018 - ArcelorMittal (referred to as "ArcelorMittal" or the "Company") (MT (New York, Amsterdam, Paris, Luxembourg), MTS (Madrid)), the worlds leading integrated steel and mining company, today announced results[1] for the three month and twelve month periods ended December 31, 2017.

- Gross debt of $12.9 billion as of December 31, 2017. Net debt decreased to $10.1 billion as of December 31, 2017, lower as compared to $12.0 billion as of September 30, 2017 and $11.1 billion as of December 31, 2016

- The Company will continue to prioritize deleveraging and believes that $6 billion is an appropriate net debt target that will sustain investment grade metrics even at the low point of the cycle

- The Company will continue to invest in opportunities that will enhance future returns. By investing in these opportunities with focus and discipline, the cash flow generation potential of the Company is expected to increase

- The Board has agreed on a new dividend policy which will be proposed to the shareholders at the AGM in May 2018. Given the current deleveraging bias, dividends will begin at $0.10/share in 2018 (paid from 2017 results). Once it achieves net debt at or below its target, the Company is committed to returning a portion of annual FCF to shareholders

Outlook and guidance:

- Market conditions are favorable. The demand environment remains positive (as evidenced by the continued high readings from the ArcelorMittal weighted PMI) and steel spreads remain healthy.

- The Company expects cash needs of the business (capex, interest, cash taxes, pensions and other cash costs) excluding working capital investment to increase in 2018 to approximately $5.6 billion. The expected increase in capex to $3.8 billion in 2018 from $2.8 billion in 2017 largely reflects the Mexico HSM project, anticipated ILVA capex, as well as other projects.

"The combination of improving market fundamentals and delivery against our strategic objectives contributed to a successful year for the Company. Action 2020 has delivered half of its targeted EBITDA gains and we have succeeded in transforming the Companys balance sheet. While we will retain a deleveraging bias, we are also investing selectively in opportunities that will strengthen the foundations of sustainable value creation. The market environment remains supportive but the industry must continue to address the twin challenges of overcapacity and unfair trade."

Corporate responsibility and safety performance

Health and safety - Own personnel and contractors lost time injury frequency rate

Health and safety performance based on own personnel figures and contractors lost time injury frequency (LTIF) rate, improved to 0.78x for the twelve months of 2017 ("12M 2017") as compared to 0.82x for the twelve months of 2016 ("12M 2016").

LTIF deteriorated to 0.87x in the fourth quarter of 2017 ("4Q 2017") as compared to 0.67x in the third quarter of 2017 ("3Q 2017"), and 0.84x for the fourth quarter of 2016 ("4Q 2016").

The Companys efforts to improve its Health and Safety record remains focused on both further reducing the rate of severe injuries and preventing fatalities.

- The designs for ArcelorMittal new Luxembourg headquarters, announced in December 2017, represent a leading demonstration of steels role in the circular economy (in which industrial strategies shift away from the linear use of materials and carbon, to a more closed-loop cycle). The design - by architects Wilmotte & Associes, who worked closely with our Global R&D team - ensures that the building can be dismantled, and nearly all the steel products re-used in a new building without the need for recycling.

- The worlds most prestigious award programme for the circular economy, The Circulars, has highly commended ArcelorMittal for demonstrating circular economy principles in its business, including innovation in the utilisation of waste gases and by-products, scrap recovery, and new business models in collaboration with internal experts, academics, partner companies and its customers.

- We successfully piloted the ResponsibleSteel standards at several sites in 2017.

Analysis of results for the twelve months ended December 31, 2017 versus results for the twelve months ended December 31, 2016

Total steel shipments for 12M 2017 increased +1.6% to 85.2Mt as compared to 83.9Mt for 12M 2016. On a comparable basis, excluding shipments from assets sold during the comparable period i.e. sale of long steel producing subsidiaries in the US (LaPlace and Vinton) and Zaragoza in Spain, and excluding the impact of the optimization at Zumarraga in Spain (Europe segment) total steel shipments in 12M 2017 increased by +2.3% as compared to 12M 2016.

Depreciation of $2.8 billion for 12M 2017 was higher as compared to $2.7 billion for 12M 2016. FY 2018 depreciation is expected to increase to approximately $2.9 billion primarily due to anticipated foreign exchange impacts.

Impairment charges for 12M 2017 were $206 million related to a downward revision of cash flow projections across all steel facilities in ArcelorMittal South Africa as compared to impairment charges for 12M 2016 of $205 million of which $49 million related to the sale of ArcelorMittal Zaragoza in Spain[4] and $156 million related to the Vanderbijlpark and Saldanha plants in South Africa.

Exceptional income for 12M 2017 was nil. Exceptional income for 12M 2016 was $832 million relating to a one-time gain on employee benefits following the signing of the new US labour contract[5].

Operating income for 12M 2017 was $5.4 billion as compared to $4.2 billion for 12M 2016. Operating income for 12M 2016 was positively impacted by exceptional income as discussed above.

Income from associates, joint ventures and other investments in 12M 2017 was $448 million as compared to $615 million in 12M 2016. Income in 12M 2017 includes a gain from disposal of ArcelorMittal USAs 21% stake in the Empire Iron Mining Partnership[6] ($133 million) and improved performance of Calvert and Chinese investees, offset in part by a loss on dilution of the Companys stake in China Oriental[7] and the recycling of cumulative foreign exchange translation losses incurred following disposal of the 50% stake in Kalagadi ($187 million)[8]. The income in 12M 2016 was primarily due to the gain on disposal of stakes in Gestamp[9] ($329 million) and Hunan Valin[10] ($74 million) as well as positive contribution of the Calvert joint venture, Chinese and Spanish investees, offset in part by impairments of the primary steel making assets at China Oriental.

Net interest expense was lower at $823 million in 12M 2017, as compared to $1,114 million in 12M 2016, driven by debt reduction including early bond repayments. The Company expects full year 2018 net interest expense of approximately $0.6 billion.

Foreign exchange and other net financing losses were $52 million for 12M 2017 as compared to losses of $942 million for 12M 2016. Foreign exchange and other net financing losses for 12M 2017 include foreign exchange gains of $546 million as compared to foreign exchange loss of $3 million in 12M 2016, mainly on account of USD depreciation of 13.8% against the Euro (versus USD appreciation against the Euro of 3.2% in prior period). These foreign exchange gains and losses are largely non-cash and primarily relate to the change of the USD exchange rate on the Euro denominated deferred tax assets, partially offset by the impact on Euro denominated debt. 12M 2017 includes non-cash mark-to-market gains on derivatives (primarily mandatory convertible bonds call options following the market price increase in the underlying shares) totalling $0.8 billion as compared to $0.2 billion in 12M 2016. In addition, 12M 2017 includes mark-to-market losses on a derivative relating to a pellet purchase agreement in the US of $0.3 billion[11]. Foreign exchange and other net financing losses for 12M 2017 and 12M 2016 also include $389 million and $399 million, respectively, for premium expense on the early redemption of bonds. In addition, 12M 2016 includes $0.1 billion non-cash expense in connection with the issuance of shares in the context of the B-BBEE transaction in South Africa[12].

ArcelorMittal recorded an income tax expense of $0.4 billion for 12M 2017 as compared to $1.0 billion for 12M 2016. The tax expense in 12M 2016 includes derecognition of deferred tax assets (DTA) amounting to $0.7 billion in Luxembourg (related to revised expectations of DTA recoverability in US dollar terms).

ArcelorMittals net income for 12M 2017 was $4.6 billion, or $4.48 earnings per share, as compared to net income in 12M 2016 of $1.8 billion, or $1.87 earnings per share.

Analysis of results for 4Q 2017 versus 3Q 2017 and 4Q 2016

Total steel shipments in 4Q 2017 were 3.3% lower at 21.0Mt as compared with 21.7Mt for 3Q 2017 primarily due to lower steel shipments in NAFTA (-8.9%) and ACIS (-3.2%), offset in part by improvements in Brazil (+3.8%).

Depreciation for 4Q 2017 was higher at $747 million as compared to $690 million for 3Q 2017 and $696 million in 4Q 2016.

Impairment charges for 4Q 2017 were $160 million related to a downward revision of cash flow projections across all steel facilities in ArcelorMittal South Africa.

Income from associates, joint ventures and other investments for 4Q 2017 includes positive contribution from Calvert and Chinese investees. Income from associates, joint ventures and other investments for 3Q 2017 includes a gain on disposal of ArcelorMittal USAs 21% stake in the Empire Iron Mining Partnership ($133 million) and positive contribution from Calvert and Chinese investees offset in part by the recycling of the cumulative foreign exchange translation losses following the disposal of the 50% stake in Kalagadi ($187 million).

Net interest expense in 4Q 2017 was $188 million as compared to $205 million in 3Q 2017 and $221 million in 4Q 2016. Net interest expense was lower in 4Q 2017 as compared to 3Q 2017 and 4Q 2016, primarily due to early bond repayment via debt tenders and bond repaid at maturity.

Foreign exchange and other net financing losses in 4Q 2017 were $261 million as compared to gains of $132 million for 3Q 2017 and losses of $278 million in 4Q 2016. For 4Q 2017, a foreign exchange gain of $83 million was recorded (as compared to a gain of $181 million for 3Q 2017) mainly on account of a 1.6% depreciation of the USD against the Euro (versus 3.5% depreciation in 3Q 2017). Both 4Q 2017 and 3Q 2017 include non-cash mark-to-market gains on derivatives (primarily mandatory convertible bonds call options following the market price increase in the underlying shares) of $174 million and $327 million, respectively. In addition, 4Q 2017 includes mark-to-market losses on a derivative relating to a pellet purchase agreement in the US of $0.3 billion.

ArcelorMittal recorded an income tax benefit of $119 million for 4Q 2017 as compared to an income tax expense of $71 million for 3Q 2017 and an income tax benefit of $13 million in 4Q 2016. The tax benefit of 4Q 2017 is the result of recording a deferred tax asset of $275 million in Luxembourg following expectation of higher future taxable profits.

ArcelorMittal recorded a net income for 4Q 2017 of $1,039 million, or $1.02 earnings per share, as compared to a net income for 3Q 2017 of $1,205 million, or $1.18 earnings per share, and a net income for 4Q 2016 of $403 million, or $0.40 earnings per share.

NAFTA segment crude steel production decreased by 5.2% to 5.6Mt in 4Q 2017 as compared to 5.9Mt for 3Q 2017 primarily due to an operational issue in Mexico, a planned maintenance in Dofasco and a market slowdown in the US.

Steel shipments in 4Q 2017 decreased by 8.9% to 5.2Mt as compared to 5.7Mt in 3Q 2017, driven primarily by decrease in volumes in flat and long products on account of a weak market.

Sales in 4Q 2017 declined by 7.3% to $4.3 billion as compared to $4.6 billion in 3Q 2017, primarily due to lower steel shipment volumes as discussed above, offset in part by higher average steel selling prices +0.8% (primarily in long products +1.5%).

Operating income in 4Q 2017 decreased to $155 million as compared to $256 million in 3Q 2017 and $164 million in 4Q 2016.

(a) Own iron ore and coal production not including strategic long-term contracts.

(b) Iron ore and coal shipments of market-priced based materials include the Companys own mines, and share of production at other mines, and exclude supplies under strategic long-term contracts.

Own iron ore production in 4Q 2017 increased by 1.4% to 14.4Mt as compared to 14.2Mt in 3Q 2017. During 4Q 2017, iron ore production in ArcelorMittal Mines Canada[13] (AMMC) was negatively impacted by mine pit wall instability issues. Despite weather related delays at the start of the quarter, Liberia production increased and achieved its full 5Mt run-rate in December 2017. Own iron ore production in 4Q 2017 increased by 3.7% as compared to 4Q 2016 primarily due to increased production in Mexico (following the restart of the Volcan mine in February 2017) and Liberia offset by lower production in AMMC.

Market-priced iron ore shipments in 4Q 2017 decreased by 7.2% to 8.4Mt as compared to 9.1Mt in 3Q 2017, primarily driven by lower shipments in AMMC impacted by poor weather conditions. Market-priced iron ore shipments in 4Q 2017 increased by 3.8% as compared to 4Q 2016 driven by increased shipments in Mexico (following restart of Volcan mine in February 2017) and Liberia.

12M 2017 market-priced iron ore shipments grew by 6.1% versus 12M 2016. Market-priced iron ore shipments are expected to grow by approximately 10% in FY 2018 versus 12M 2017, primarily due to the ramp up of the Liberia mines (expected to grow by approximately 3Mt on a full year basis to 5Mt in 12M 2018).

Own coal production in 4Q 2017 decreased by 1.4% to 1.5Mt as compared to 3Q 2017 primarily due to lower production in Kazakhstan. Own coal production in 4Q 2017 decreased by 16.1% as compared to 4Q 2016 primarily due to lower production in Kazakhstan and at Princeton (US) mines.

Market-priced coal shipments in 4Q 2017 was stable at 0.6Mt as compared to 3Q 2017. Market-priced coal shipments in 4Q 2017 decreased by 34.5% as compared to 4Q 2016 primarily due to decreased shipments at Kazakhstan driven mainly by geological issues and lower yield.

Operating income in 4Q 2017 decreased to $159 million as compared to $238 million in 3Q 2017, and $203 million in 4Q 2016, primarily for the reasons discussed.

EBITDA in 4Q 2017 decreased by 21.8% to $267 million as compared to $341 million in 3Q 2017, primarily due to decreased seaborne iron ore reference prices (-8.1%) and lower market-priced iron ore shipments (-7.2%). EBITDA in 4Q 2017 was lower as compared to $297 million in 4Q 2016, primarily due to lower seaborne iron ore reference prices (-7.1%) and lower coal shipments, offset in part by higher market-priced iron ore shipment volumes (+3.8%).

Liquidity and Capital Resources

For 4Q 2017, net cash provided by operating activities was $2,885 million as compared to $763 million in 3Q 2017 and $1,653 million in 4Q 2016. The higher net cash provided by operating activities during 4Q 2017 reflects in part a working capital release of $1,657 million, as compared to an investment of $801 million in 3Q 2017 and a release of $495 million in 4Q 2016.

Net cash used in investing activities during 4Q 2017 was $931 million as compared to $563 million during 3Q 2017 and to $809 million in 4Q 2016. Capital expenditure increased to $1,036 million in 4Q 2017 as compared to $637 million in 3Q 2017 and to $802 million in 4Q 2016. FY 2018 capital expenditure is expected to be $3.8 billion.

Cash provided by other investing activities in 4Q 2017 of $105 million primarily includes tangible asset disposals and disposal proceeds of US long products (Georgetown). Cash provided by other investing activities in 3Q 2017 of $74 million primarily includes the first installment proceeds from disposal of ArcelorMittal USAs 21% stake in the Empire Iron Mining Partnership ($44 million).

Net cash used by financing activities in 4Q 2017 includes $1.2 billion of bonds repurchased in October pursuant to cash tender offers, $0.6 billion (EUR540 million) repayment at maturity of the euro 4.625% Notes due November 17, 2017, $644 million used to early redeem in December the 6.125% Notes due June 1, 2018 and partial repayment of borrowings offset in part by a new $0.4 billion (EUR300 million) Schuldschein loan in October and $0.6 billion (EUR500 million) euro 0.95% bond due January 17, 2023 issued in December. Net cash provided by financing activities in 3Q 2017 includes borrowings and commercial paper, offset in part by a $0.5 billion repayment of the asset-based revolving credit facility at ArcelorMittal USA. Net cash used in financing activities for 4Q 2016 primarily includes repayments of a $0.3 billion loan and $0.5 billion of short term facilities, offset in part by a $0.3 billion increase in commercial paper issuances.

During 4Q 2017, the Company paid dividends of $21 million primarily to minority shareholders in Bekaert (Brazil) as compared to $80 million in 3Q 2017 and $7 million in 4Q 2016.

As of December 31, 2017, the Companys cash and cash equivalents amounted to $2.8 billion as compared to $3.0 billion at September 30, 2017 and $2.6 billion at December 31, 2016. Gross debt decreased to $12.9 billion as of December 31, 2017, as compared to $14.9 billion at September 30, 2017 and $13.7 billion at December 31, 2016.

As of December 31, 2017, net debt decreased to $10.1 billion as compared with $12.0 billion at September 30, 2017 primarily due to positive free cash flow ($1.8 billion), and lower as compared to $11.1 billion as of December 31, 2016 due to positive free cash flow ($1.7 billion) offset in part by negative foreign exchange impacts on Euro-denominated debt ($0.7 billion).

As of December 31, 2017, the Company had liquidity of $8.3 billion, consisting of cash and cash equivalents of $2.8 billion and $5.5 billion of available credit lines[14]. The $5.5 billion credit facility contains a financial covenant of 4.25x Net debt / EBITDA (as defined in the facility). On December 31, 2017, the average debt maturity was 4.6 years.

ArcelorMittals employee benefit net liabilities decreased from $8.1 billion at December 31, 2016 to $7.5 billion at December 31, 2017 following the increase of the return on plan assets as well as impact of other actuarial assumptions partially offset by the increase of the defined benefit obligation due to decreased discount rates.

Action 2020 progress

The Company has made measurable progress on its strategic Action 2020 plan resulting in $0.6 billion of contribution to 2017 operating results, bringing the cumulative benefit to $1.5 billion.

We are approximately one-half of the way along the Action 2020 journey with all segments contributing to the progress. The savings achieved in 2017 include volume contribution ($0.3 billion) as well as a combination of cost and product mix improvements ($0.3 billion). Volume is a key component of Action 2020 (5Mt volume improvement) and we expect to see more progress in this area in 2018 and beyond, assuming market conditions remain favorable.

- Europe: The transformation program has progressed well. Savings at the cluster-leading plants continue to be made, with changes to the operating model to restructure and modernise the organisation now well embedded. The organisation is benefiting from a more integrated, centrally co-ordinated approach, further reducing costs. Additional gains are being made with enhanced use of and investment in digitalisation in the manufacturing process, supply chain and commercial teams. Overall, net volume gains and improved mix contributed with higher hot strip mill production offset in part by lower volumes caused by operational issues primarily in the long business.

- NAFTA: Indiana Harbor footprint optimization has been completed: Savings achieved came from headcount rationalization and efficiencies following closure of its 84" hot strip mill (HSM), idling of the No.2 steel shop, ongoing benefits from a new caster at No.3 steel shop. Restoration of the 80" HSM and Indiana Harbor finishing will continue in 2018. Volume gains have been offset in part by lower automotive sales.

- ACIS: Ukraine benefited from the construction of a new coke oven battery #6 and other PCI/energy saving initiatives. Improving operational performance in Kazakhstan with production records during the year was offset by lower shipment volumes in Ukraine.

- On December 15, 2017, ArcelorMittal announced the extension of the conversion date for the $1.0 billion privately placed mandatory convertible bond (MCB) issued on December 28, 2009 by one of its wholly-owned Luxembourg subsidiaries. This amendment to the MCB, which is mandatorily convertible into preferred shares of such subsidiary, was executed on December 14, 2017. The mandatory conversion date of the bond has been extended to January 29, 2021. The other main features of the MCB remain unchanged. The bond was placed privately with Credit Agricole Corporate and Investment Bank and is not listed. The subsidiary has simultaneously executed amendments providing for the extension of the outstanding Notes into which it invested the proceeds of the bond issuance, which are linked to shares of the listed companies Eregli Demir Va Celik Fab. T. AS of Turkey and China Oriental Group Company Limited, both of which are held by ArcelorMittal subsidiaries.

- On December 13, 2017, ArcelorMittal and the "Fonds dUrbanisation et dAmenagement du Plateau de Kirchberg," ("the Fonds Kirchberg") announced that the architectural firm Wilmotte & Associes ("W&A") was the winner of the architectural consultation to design ArcelorMittals new global headquarters building in Luxembourg. W&A was selected by a nine-person jury chaired by Aditya Mittal, CFO of ArcelorMittal and CEO of ArcelorMittal Europe, following a highly competitive process with designs proposed by many of the worlds leading architects. The ambitious winning design is primarily steel, and will showcase the diverse benefits of steel over other building materials in addition to highlighting the use of steel in green, sustainable construction. As well as being ArcelorMittals headquarters, housing around 800 employees, some of the space will be leased for other uses. There will also be a restaurant, sports facility and a 200-seat auditorium available to the public.

- On December 4, 2017, ArcelorMittal announced the issuance of EUR500 million 0.95%. Notes due January 17, 2023. The Notes were issued under ArcelorMittals EUR10 billion wholesale Euro Medium Term Notes Programme. The proceeds of the issuance were used for general corporate purposes, including the refinancing of existing debt (such as the 6.125% Notes due June 1, 2018 being early redeemed on December 28, 2017).

- On November 28, 2017, ArcelorMittal confirmed that it had given notice that it would redeem all of the then outstanding U.S. $643.5 million of its U.S. $1.5 billion 6.125% Notes due June 1, 2018. The settlement occurred on December 28, 2017, with total cash spent of $658 million including accrued interest and premium on early repayment.

Market conditions are favorable. The demand environment remains positive (as evidenced by the continued high readings from the ArcelorMittal weighted PMI) and steel spreads remain healthy.

Global apparent steel consumption ("ASC") is estimated to have expanded by +3.2% in 2017. Based on the current economic outlook, ArcelorMittal expects global ASC to grow further in 2018 by between +1.5% to +2.5%. By region: ASC in US is expected to grow +1.5% to +2.5% in 2018 (including pipes and tubes) (versus +1.3% in 2017) driven by demand in machinery and construction. In Europe, we expect underlying demand to continue to grow, supported by the strength of machinery and construction end markets, and overall demand is expected to be +1.0% to +2.0% in 2018 (versus growth of 1.5% in 2017). In Brazil, ASC is expected to grow by +6.5% to +7.5% in 2018 (an acceleration of growth versus +4.6% in 2017), as the economy starts to turnaround with improved consumer confidence and pick up in longs as construction recovers. In the CIS, ASC is estimated to grow +2.0% to +3.0% in 2018 (a moderation of growth versus +5.4% in 2017). In China, ASC grew by +3.5% in 2017, higher than our initial expectations. Overall demand is expected to remain close to this level in 2018 (between -0.5% to +0.5%), as the anticipated weakness in the real estate sector is expected to be offset in part by robust infrastructure and automotive end markets. Nevertheless, ex-China ASC is expected to grow by approximately +3.0% to +4.0% in 2018 (versus +2.8% in 2017), which supports global ASC growth of +1.5% to +2.5% in 2018 (as compared to growth of ~3.2% in 2017).

The Company expects cash needs of the business (excluding working capital investment) to increase in 2018 to approximately $5.6 billion from $4.4 billion in 2017. The expected increase in capex to $3.8 billion in 2018 from $2.8 billion in 2017 largely reflects the Mexico HSM project and anticipated ILVA capex as well as additional strategic projects (including further investment to enhance downstream optimization in Europe). Net interest is expected to decline to $0.6 billion from $0.8 billion in 2017 reflecting the benefits of liability management exercises completed in 2017. Other cash needs are expected to increase to $1.2 billion from $0.8 billion in 2017, primarily on account of higher expected cash taxes due to timing impacts.

- In support of the Companys Action 2020 program that was launched at its fourth quarter and full-year 2015 earnings announcement, the footprint optimization project at ArcelorMittal Indiana Harbor is now complete, which has resulted in structural changes required to improve asset and cost optimization. The plan involved idling redundant operations including the #1 aluminize line, 84" hot strip mill (HSM), and #5 continuous galvanizing line (CGL) and No.2 steel shop (idled in 2Q 2017) whilst making further planned investments totalling ~$200 million including a new caster at No.3 steelshop (completed in 4Q 2016), restoration of the 80" hot strip mill and Indiana Harbor finishing are ongoing. The full project scope is expected to be completed in 2018.

- On September 28, 2017, ArcelorMittal announced a major US$1 billion, three-year investment programme at its Mexican operations, which is focussed on building ArcelorMittal Mexicos downstream capabilities, sustaining the competitiveness of its mining operations and modernising its existing asset base. The programme is designed to enable ArcelorMittal Mexico to meet the anticipated increased demand requirements from domestic customers, realise in full ArcelorMittal Mexicos production capacity of 5.3 million tonnes and significantly enhance the proportion of higher-value added products in its product mix, in-line with the Companys Action 2020 strategic plan. The main investment will be the construction of a new hot strip mill. Construction will take approximately three years and, upon completion, will enable ArcelorMittal Mexico to produce c. 2.5 million tonnes of flat rolled steel, long steel c. 1.8 million tonnes and the remainder made up of semi-finished slabs. Coils from the new hot strip mill will be supplied to domestic, non-auto, general industry customers. The project commenced late 4Q 2017 and is expected to be completed in the second quarter of 2020. The Company expects capital expenditures of approximately $350 million with respect to this programme in 2018.

- Although the Monlevade wire rod expansion project and Juiz de Fora rebar expansion were completed in 2015, the Juiz de Fora melt shop project is currently on hold and is expected to be completed upon Brazil domestic market recovery, and the Company does not expect to increase shipments until domestic demand improves.

- ArcelorMittal Liberia is moving ore extraction from its depleting DSO (direct shipping ore) deposit at Tokadeh to the nearby, low strip ratio and higher-grade DSO Gangra deposit where planned ramp up has progressed, reaching a 5Mt run rate at the end of December 2017. Following a period of exploration cessation caused by the onset of Ebola, ArcelorMittal Liberia recommenced drilling for DSO resource extensions in late 2015. During 2016, the operation at Tokadeh was right-sized to focus on its "natural" Atlantic markets. The nearby Gangra deposit has now been developed as part of the staged approach as opposed to the originally planned phase 2 step up to 15Mtpa of concentrate sinter fine ore product that was delayed in August 2014 due to the declaration of force majeure by contractors following the Ebola virus outbreak, and then reassessed following rapid iron ore price declines over the period since. The Gangra mine, haul road and related existing plant and equipment upgrades are nearing completion. ArcelorMittal remains committed to Liberia where it operates a full value chain of mine, rail and port and where it has been operating the mine on a DSO basis since 2011. The Company believes that ArcelorMittal Liberia presents a strong, competitive source of product ore for the international market based on continuing DSO mining and then moving to a long-term sinter feed concentration phase.

Exceptional income / (charges): relate to transactions that are significant, infrequent or unusual and are not representative of the normal course of business such as restructuring costs or asset disposals.

LTIF: lost time injury frequency rate equals lost time injuries per 1,000,000 worked hours, based on own personnel and contractors.

MT: Refers to million metric tonnes

Market-priced tonnes: represent amounts of iron ore and coal from ArcelorMittal mines that could be sold to third parties on the open market. Market-priced tonnes that are not sold to third parties are transferred from the Mining segment to the Companys steel producing segments and reported at the prevailing market price. Shipments of raw materials that do not constitute market-priced tonnes are transferred internally and reported on a cost-plus basis.

Mining segment sales: i) "External sales": mined product sold to third parties at market price; ii) "Market-priced tonnes": internal sales of mined product to ArcelorMittal facilities and reported at prevailing market prices; iii) "Cost-plus tonnes" - internal sales of mined product to ArcelorMittal facilities on a cost-plus basis. The determinant of whether internal sales are reported at market price or cost-plus is whether the raw material could practically be sold to third parties (i.e. there is a potential market for the product and logistics exist to access that market).

Net debt: long-term debt, plus short-term debt less cash and cash equivalents (including those held as part of liabilities held for sale).

On-going projects: Refer to projects for which construction has begun (excluding various projects that are under development), even if such projects have been placed on hold pending improved operating conditions.

Operating results: Refers to operating income/(loss).

Operating segments: The NAFTA segment includes the Flat, Long and Tubular operations of USA, Canada and Mexico. The Brazil segment includes the Flat operations of Brazil, and the Long and Tubular operations of Brazil and its neighboring countries including Argentina, Costa Rica and Venezuela. The Europe segment comprises the Flat, Long and Tubular operations of the European business, as well as Downstream Solutions. The ACIS segment includes the Flat, Long and Tubular operations of Kazakhstan, Ukraine and South Africa. Mining segment includes iron ore and coal operations.

Own iron ore production: Includes total of all finished production of fines, concentrate, pellets and lumps (excludes share of production and strategic long-term contracts).

Working capital: trade accounts receivable plus inventories less trade and other accounts payable.

YoY: Refers to year-on-year.

In addition, certain percentages presented in the tables in this press release reflect calculations based upon the underlying information prior to rounding and, accordingly, may not conform exactly to the percentages that would be derived if the relevant calculations were based upon the rounded numbers. This press release also includes certain non-GAAP financial measures. ArcelorMittal presents EBITDA, and EBITDA/tonne, which are non-GAAP financial measures and defined in the Condensed Consolidated Statement of Operations, as additional measurements to enhance the understanding of operating performance. ArcelorMittal believes such indicators are relevant to describe trends relating to cash generating activity and provides management and investors with additional information for comparison of the Companys operating results to the operating results of other companies. ArcelorMittal also presents net debt as an additional measurement to enhance the understanding of its financial position, changes to its capital structure and its credit assessment. ArcelorMittal also presents free cash flow, which is a non-GAAP financial measure defined in the Condensed Consolidated Statement of Cash flows, because it believes it is a useful supplemental measure for evaluating the strength of its cash generating capacity. Non-GAAP financial measures should be read in conjunction with and not as an alternative for, ArcelorMittals financial information prepared in accordance with IFRS. Such non-GAAP measures may not be comparable to similarly titled measures applied by other companies.
